PPP: removeEventListener doesnt seem to remove listener

I have an application which dials out from a TINI box and after conducting a
socket transaction closes the PPPClient. It then attempts to dial out again
after a couple of minutes. I can only do this twice after which I get an
OutofMemory exception. Even if I retry after a "System.gc()", I have the
same problem

I am using a modified version of the PPPClient example which comes with
TINI.

I tried two approaches and have problems with both

1) Creating a new PPP object every time I dial out. This results in Out of
memory exception as explained above.

2) Reusing the same PPP object. In this case I used removeEventListener
while shutting down the PPPClient and addEventListener when I start it. But
each time (after the first time) I call addEventListener TINI's ppp
complains that there are too many listeners. It looks like
removeEventListener doesn't remove the listeners properly. If I ignore this
error and let it proceed PPP doesn't work correctly. It seems to get
connected to the ISP but there is no "UP" event generated.

<While dialing out second time>

Dialing
Connected to ISP
<cant communicate via PPP>
PPP IS DOWN

<Dialing out first time>
Dialing
Connected to ISP
PPP IS UP
<communication with PPP successful. ...socket transactions take place here>
PPP IS DOWN

I did search through the archives and found a post about a bug in
removeEventListener but that post was from more than a year ago.

I would appreciate any help/suggestions/pointers/example code.

Thanks
Prashant
